, Be it known that I, FREDERIC R. BARKER,

l a: subject of King'George V of England,

residing at Boston, in the county of Suffolk .-.and State of .Massachusetts, have invented new andv'useful Improvements in Wheel- Rims, of which the following is a specifica:

- This invention relates toimprovements in- 10- Wheel rims and particularly rims intended for use in connection with pneumatic tires.

There are now in use two types of rims,

one known: as demountable rims and the other asquick-detachable .rinis,,although the latter might be appropriately called divisible rims. In the useof demountable rims,it

' is customary to have one or more spare rims with ready-inflated tires thereon so that 1n. case of a puncture or other 1n ury to one of the tires-in use on the vehicle the injured "tire with its rim may be removed and replaced b another demountable rim and readyi ated tire. In the so-called quick detachable ordivisible rims, there is pro- '-vided a ringcommonly called a bead which is detachable'from the rimto allow. the tire to be removedin order that the inner tube may be removed from the outer casing or,-

shoe for repair car replacement. p

The object .of my invention is to provide improved means for facilitating the attaching of a demountable rim or attaching a bead to the permanent rim.

appear hereinafter. p To these ends, my invention consists 111' ticularly pointed out in the claims.

Still other objects and advantages will the'novel features of constructionand in the combination-and arrangement of parts" .set forth in the following specification and par Referring tothe drawings:. IF1gur-e..l is

'Fig.-2 is an enlarged -de-' tail side elevation of aportion of the rim, tire and wheel showingthe means. terse curing the'demountablerim to the permanent rim.' 1 Fig.3 is a sectional view taken 'on line. of Fig.2, looking towardthe mg mounted thereon a demountable rim.

hereinafter referred to as ringsonbeads' Fig. is a sectional view similar to. Fig. 4, showing. the retaining ring in expanded position preparatory toremoving the same. 1g. 6 IS a sectional view-of the rimasarranged fora straight side'tire. Fig. 7? is-a sectional view takenon line 7--7 of Fig.

2, looking in the direction of the arrow on In the drawings, 10 is a wheel which may be of any'usual or desired constructionhavmg secured'to its periphery a'rini-ll which will be referred'to as the'permanent rim, since it remains attached to the wheel ltlounted uppn this permanent. rim is a removable rim which may be composed ofa plurality of pieces, as shown in Figs. 3 and v 6, or may consist of a single piece, as shown in Figs. 4 and 5, the principle. being the same in both cases.

Referring to Figs. 3 and 6, morepar ticularly to Fig. 3, the'removable rim shown therein is composed of a plurality of parts 12-, 13 and 14: which receive atire 15 of the clencher type, these parts surrounding and being mounted upon the permanent rim 11.

The tire 15 is provided as usual with an inner tube 16. The parts 12 and '14 will and the part 13 will be referred to as a band.

The ring or head 12 is: provided. with a lip 17 and the ring or bead-'14 is 'rovided of the tire rests upon the band. 13. Preferably, this band is-mad-e as light vas possible:

andto that end is preferably provided at intervals'with suitable recesses .19, see Fig.1

ice I 2, and may be made of aluminum which has the advantage of being not only ligh't, but

wit-ha similar lip 18-bothlofwhic engage the tire in the usual manner, while thebase non-corrosive as well and, therefore, will not rustonto the base of. the tire. :The ring or head 141s also-preferably made as light as possible and to t atend is preferably formed hollow, as shown'iniFi 3, and may-alsobe made'of aluminum, if esired.

The permanent rim-'11 1S preferably pra vided at one side with a circumferential flange and at its other side is preferably provided with thee-t er,

provided with a circumferential groove 21. The flange 20 forms an-abutment for a ring 22 having a laterally inclined outer circumferential surface 23 against which the inner laterally inclined circumferential surface oil the bead or ring 12 restsf The ring 22'is preferably made separate from the permanent rim 11 so as to be capable of being removed and reversed to occupy the position shown in Fig. 6' for use with-a tire 24 of the straight side type, in which case the head 12 will also be reversed so that its lip 17 will be turned outwardly.

The ring or head 14 is preferably held'in place by a ring 25 prefera ly provided with a lateral recess 26 to receive'the head 14 and referably this recess is provided with an inner laterally inclined'circumferential surface 27 which fits against a correspondingly shaped circumferential surface of the head 14, as shown in. Fig. 3. Preferably, the

head or ring 14 and the ring 25 are both expansible and contractible and to this end are preferably interrupted, or, in other words, provided with a slot 28, see Figs. 2 and 7, and preferably both rings are so made that when released theywill expand readily. Preferably, the head 14 and ring. 25 are suitable means to prevent relative circumferential movement and for this purpose I prefer to employ two dowel ins 29 and 30 secured to one ring and proectin into corresponding perforationsin in the present instance, said pins being secured to the bead 14. The rings 14 and 25 are provided with suitable means'for changing their diameters and for this puri. F as Thu 11, see particularly Fig. 2, this slot pose. I preferably employ the mechanismwhich I will now proceed to describe. is provided with two lugs 31 posite sides of the slot beingpreferably open along its outer side.-

pThe iu isi is. preferably provided. with a recess 34 and the lug 32 with a correspondirig recess 35, the

. .mhble abutment 36 preterabl rim 11 and tulcrumedon a pivot 39-upon a recess 34 receiving a su1tconsisting of a stud having screw-three ed engagement with a lug 37 on the permanent rim 11 so as to he ca able of being adjusted to vary the A force. 0 the clampin mechanism, as will hereinafter appear.

he recess receives shaped end of a lever the correspondingly with the 38 preferably formed concentric,

pair of links 40, said links being il'ulcrumedupon a pivot'41 upon the. stud The lever 38'1s interposedbetween t helinks 40' and the lugs 31 and 32 are alehinterposed between said links- Y The mechanismf ust describe/d constitutes a powerful togglewhich, when'swung from ,vided wit similar incense the positionshown in dotted lines in Fig. 2 i to the position shown in full lines therein,

will very forcibly draw the lugs 31'and 32 towardeach other, thus contracting the ring 25. This serves to lock the ring 25 and hold the head 14 in place.

- Preferably, the fulcrum 39, the fulcrum 41 and the end of the lever 38 engaging the lug 32 as a fulcrum all lie in a substantially straight line so that the toggle naturally tendsyto remain locked in its normal position. As an additional safeguard, however,

I provide a suitable spring-pressed latch 42 inter'engaging with the lever'38 in a suitable manner, preferably by providing said lever with a recess 43 in its end to receive the latch 42 and preferably. said lever, is provided with an inclined surface 44 adjacent to and inclined toward said recess for the purpose of automatically retracting the latch when the lever 38 is swung into its normal position, in which case the latch. will ride up the incline 44 and snap into the recess 43' under the influence of a suitable spring 45.

The latch 42 is preferably mounted-toslide in a lug 46 on the permanent rim 1-1, a

said lug being preferabl provided with-a I lateral slot 47 and'said atch being prefer ably provided with a lateral; recess 48 which is accessible through said. slot so that some.

suitable instrument may be inserted through the latch maybe withdrawnfrom the recess 43. The latch 42 which is preferably cylindrical in form held against rotation by suitable means such, for example, as a cotter. pin 49 located in a slot 50 provided in the, lug 46, this cotter -.p1nalso serving as a cling too farunder the .infiuence' ofthe means for preventing said latch from tray-- spring 45.

The in the lug 37 is provided with a correspond the slot. 47 into the recess.- 48 in-order that I .31and are preferably pro- I projections51' and 52 and ingly shaped recess 53' to receive the .lug 51 orto receive the'lug 52 in case the ring 25;

should be removed and reversed so as to 00- '1"- cupy the position shown in Fig.6, which po-l. '1

sit-ion said ring occu ies when used. incon-"f nection with a tire o the straight side type.

I do, not herein claim broadly thetoggle.v

mechanism just described tor contracting the rin 25, but in its broader aspects this toggle orms the subject matter of an applist 24,1910, Serial No. 578,760.

part removable rim which may he removed to ether with the tire so thatthe're may be su tit-uted therefor another tire provided with a single piece demountable rind 54 prol cation of myself and J os'eph Greenwood, filed Au its berore stated, the head 12, the band 13 and thebead 14 constitute as it werev a three- 125- clencher type. When this rim is slipped into place, it engages at one side the laterally inclined surface 23 of the ring 22 and the other side of said rim is'located in the recess 26 of'the ring and when this ring is contracted, as shown in Fig. 4, the laterally inclined inner circumferential surface 27 engages the correspondingly shaped outer circumferentialsurface of the rim 54, thus crowding said rim inwardly and toward the left. As a consequence, the rim 54 is crowded against the inclined surface 23 and is also drawn firmly against the permanent rim 11.

The recess 26, it will be observed, is of such depth radially that when the ring 25 is expanded from the position shown in Fig. 4

to the position shown in Fig. 5, the inner circumferential surface of said ring becomes substantially coincident with the outer circumferential surface of the permanent rim 11 and since the slot 33 is open at the side, said ring may then be withdrawn outwardly from its place so as to permit the removal of the demountable rim 54. It will now be evident that if the tire when arranged upon the rim, as shown in Fig. 3 should become punctured or otherwise injured so that it bep comes necessary to remove the same for repair this may be accomplished by removing the ring 25 and bead 18 and then slipping the tire 15 and band 13 from their place upon the permanent rim 11 and the tire may then be repaired and replaced. This is done if one has plenty of time and the conveniences for mak'ing the necessary repair. If, however, it is not convenient to repair the tire at the time, the bead 12 may be slipped from its place and a fresh tire ready inflated upon the rim 54 slipped on in place of the other rim and locked onto the permanent rim in a few moments time.

The rim, as before stated, also has the adbeads and rings, as shown in Fig. 6. Thus it will be evident that the rim ispractically universal.

One further advantage ,of the rim is that when the tire is removedtogether with the band 13, the tire may; remain on' the band and the band will prevent the-entrance of foreign matter into the interior ofthe tire and in this Way'the usual casing -or=protec-" tive covering for the tire may be dispensed with and the tire may be strapped on the vehicle without danger of any dirt getting into the tire. I

Having thus described my invention, what I claim and desire by Letters Patent to sewith a lateral recess accessible through said.

slot. I

2. The combination with a rim, of an expansible and contra'ct'ible ring mounted on said rim, means to change the diameter of said ring including a leverprovided with a recess and a surfaceradjacent to and inclined toward saidrecess, and a springspressedm-fl latch entering said recess and having an inclined surface adapted to engage; the first-' mentioned inclined surface to retract said latch before entering said recess. f .1
